SAUTOMATIC POWER-COMPENSATOR.

SPECIFICATION forming part of Letters Patent No. 240,287, dated April 19, 1881.

Application filed February 18,1881. (No model.)

To all whom it may concern:

Be it known that 1, KASIMIR VoGEL, of the city of Chelsea, State of Massachusetts, have invented an Improved Automatic Power-Compensator, of which the following is aspecitication.

This invention has for its object the periodical or constant restoration of the tension or strain upon a spring, or the periodical or con- I'o stant rewinding of a weight, when such weight or spring is employed as the impelling force of a clock, watch, motor, or other moving or impelling device or mechanism; and the invention consists in the combination, with a minor actuating spring or weight in a clock, watch, motor, or other moving or impelling device or mechanism, of a major spring or weight so combined, arranged, and connected to or with such minor spring or weight that as the latter is being unwound, run down, or its impelling force is being expended such major spring or weight shall, so long as its force transcends that ofsuch minor spring or weight, either intermittently or continuously restore by rewinding such minor spring or weight. To accomplish such object l employ the devices, or equivalents thereof, which are shown in the accompanying drawings, and are fully hereinafter described, and are specifically defined in 0 the appended claims.

In the accompanying drawings, Figure 1 is a'front or face elevation of a common clockmovement having my invention thereto applied. Fig. 2 is a side or edge elevation of 5 Fig. 1, taken as viewed from the right hand thereof. Fig. 3 is a side or edge elevation of Fig. 1, taken as viewed from the left in Fig. 1. Fig. 4 is a detached front elevation, showing thevibratin g pawl and coacting cam by which 0 the action of the major spring or weight upon the minor spring or weight is regulated and controlled. Fi 5 is a detached vertical diametric section, showing a modification of the devices shown in Fig. 4 by which the compen- 4 5 sation or restoration of force to the minor spring or weight is regulated. Fig. 6 is a detached front elevation of the devices shown in section in Fig. 5.

In said views 1, 2, and 3, A represents a common movement or interior mechanism of a clock, the same being introduced into said views only for the purpose of the more easily illustrating one of the practical applications of my invention. A drum, a, is loosely mounted on a rotary arbor, b, and within said drmn is arranged the major coiled spring 0, (shown in side and end elevation in Figs. 1 and 2,) said spring being at one of its ends secured to shaft 1) and at the other end to drum a by a screw,

as shown in Fig. 2, or other well-known means. Upon said shaft 1) is rigidly secured the ratchet d, with which the usual spring-actuated holding-pawl engages, as is clearly shown in Figs.

1 and 2. There is also concentrically mounted upon arbor b a gear, 6, which is secured to and revolves with drum to as the same is actuated by spring 0. Said gear 6 meshes into and actuates pinion f on shaft g, which pinion meshes into gear h, which is rigidly secured upon arbor i, the enmeshing of said gears e f h being clearly shown in Fig. 2.

The drum j, which is rigidly secured to or formed with gear k, is loosely mounted upon arbor i, and within said drum is the coiled spring 1, one end of which is secured to arbor i and the other to said drumj by a screw, as shown, or other well-known means. Said gear 70 engages with pinion a on shaft 1) of the clock-movement A, and thereby actuates the same, the meshing of said geark and pinion a being shown in Figs. 1 and 3.

The transmittal of the force of said springs c and l for the impelling of clock-movementA is effected in the following manner:

It will be apparent that by the engagement of gear 0 on drum to with the intermediate gear f and the engagement of the latter with gear h, which is rigid on arbor i, while the coiled spring Z is secured, as stated, to arbor t and drum j, and the gear is on said drum engages with pinion a on shaft 1) of clock-movement A, the force of spring a will by said means be exerted upon spring I, and the force of the latter will be exerted upon movement A when not subject to the force of spring 0,- and for 5 the purpose of intermitting or controlling the exerting by spring 0 of its force upon spring Z, I employ the following-described devices:

A bifurcated pawl having arms m n is pivotally and loosely mounted on arbor g, and a trundle mounted on the pin 0 (shown bydotted lines in the arm a) travels in the eccentric camgroove 19, in the face of gear 7r, whereby said pawl is vibrated on arbor g as gear 70 revolves. Upon the arms m a of said pawl are respectively formed the seats 1 2, as shown in Figs. 1 and 4, which seats engage the catch or tooth s of the outer cam, t, rigidly secured on arbor i, as the same revolves. If both said springs were wound to full tension and catch 8 rested in seat 1 of arm m, as shown in Fig. 4, the force of the major spring 0 would be thereby pre- "ented from acting on the minor spring 1 until, by the semi-revolution of gear 70 and the action of eccentric groove 11 upon pin 0 in arm n, seat 1 was disengaged from catch 8 of arm t, thereby setting free drum j,when theaction ofsprin g 0 will restore the tension ot'sprin g l, which, durin g such half-revolution of gear 70, was thereby expended in driving the clock-n'iovement A. When said catch .9 is so released from the seat in either arms at or 12, the seat in the opposite arm, by its contact with tooth s, will arrest the rotary movement of arbor 17, when the force of spring 1 will continue to drive the clockmovement or other attached mechanism. If each revolution of gear it moved forward the hands on the dial one hour, then by the devices shown the superior force of spring 0 would once each half-hour restore the full tension of spring I, which restoration would be so repeated as long as the strength, as exerted, of spring 0 exceeded that of spring l.

Instead ofrewinding spring Z at each halfrevolution of its drum and gear 70, it may be accomplished with any degree of frequency or infrequen cy, as may be desired orsuch rewinding may be continuous, and in the ratio of the expenditure of the force of spring I, to accomplish which result the gear knvould have a cam-groove corresponding to groove 1) in the gear is, opposite to that of gear k, while the arm m of the pawl would be provided with a cam-pin, o, like that shown at 0 on arm m, but

projecting in the opposite direction, so as to engage in the groove in the face of gear h, as shown in Fig. 5, where the contact of the pins of the arms of said pawl in their respective eccentric cam-grooves are plainly shown. By this arrangement the superior force of spring 0 can only rewind the inferior spring lby means of gear h, secured to arbor t, as the cam-gear k is rotated by the action of spring I as it actuates the clockanovement.

It will be obvious that the employment of a weight in place of either or both said springs would not change the spirit of my invention, which is equally adapted to use with either of such actuating means. And my invention is adapted to use not only upon time-keepers, but to numerous other purposes where springs or weights are employed as the motive power.

I claim as my invention 1;lhecombination,withasuperiorprimemotor and an interior motor, the two being united by suitable power-transmitting devices, of a mechanism combined and arranged therewith to automatically control and permit such superior motor to either intermittently rewind the inferior motor or to continuously rewind the same as its force in either case is expended.

2. The combination of springs c and l with suitable connecting and transmitting mechanism, cams p and t, and the bifurcated pawl, constructed and arranged to be engaged and actuated by cam p and to engage and arrest cam t, substantially as specified.

3. The combination of spring 0, with its drum to and gear 0, mounted on arbor 1), spring 1, with its drum j and gear is, mounted loosely on shaft 1', and the gear h, also mounted on shaft t' and arranged to be actuated by spring 0 by a suitable connection, and the pawl and coacting cams, all substantially as specified.

KASIMIR VOGEL.
